Barroso described the agreement as "highly ambitious" and "great importance" for the EU's economy.

"Canada is one of the most advanced economies in the world. This agreement will provide significant new opportunities for companies in the EU and in Canada by increasing market access for goods and services and providing new opportunities for European investors," Barroso said.

"It will be the basis for gaining a strong foothold in the North American market and so provide a catalyst for growth and the creation of jobs in Europe," he added.

EU Trade Commissioner Karel De Gucht commented that it has been a real challenge to reach this agreement, and it's a real first when it comes to a comprehensive Free Trade Agreement between two mature economies.

It will be the first free trade agreement between the EU and a G8 country.

According to the EU, the agreement is expected to increase bilateral trade in goods and services by 23 percent, or 26 billion euros (about $35 billion). The overall benefits of the agreement are expected to raise the level of the EU's annual GDP by some 12 billion euros a year.
